Overview
Enviro Test Construct Multi-function Earth resistance tester is also called grounding resistance tester. Its advanced grounding resistance tester integrating a variety of measurement methods, in addition to the function of the traditional auxiliary ground pole measurement and grounding resistance, the instrument also has the unique function of no auxiliary ground pole measurement. Using color display and microprocessor technology, measure the grounding resistance test by microprocessor control precision 4-line method, 3-line method, simple 2-line method, selection method and double clamp method.
Multifunctional Earth resistance tester is controlled by a microprocessor, it can accurately detect the grounding resistance, soil resistivity, grounding voltage, DC voltage, DC resistance and AC current
Multifunction Earth Resistance tester is composed of host machine, host computer software, mobile phone APP software, test line, USB cable, charger and ground pin.
